lNKING DEVICE,

SPECIFICATION Application filed April 30, 1902.

To all whom it may concern:

Be it known that I, HORACE A. Davis, a citiof New York, county of Richmond, and State of New York, have invented a new and useful Inking Device, of which the following a specification.

My invention relates to an improvement in inking devices for cylinder printing-presses. Its object is to provide for inking the type on form cylinders of cylinder printing presses continuously in each direction.

' View of the machine.

Referring to the accompanying drawings,

in which like reference characters refer to like parts of the device, Figure 1 is a diagrammatic Fig. 2 is a detail view,

' partly sectional, of the arm actuating the inking-roller. Fig. 3 is a cross-section on the line 3 3 of Fig. 2. Fig. 4 is a detail view of the journals of the inking roller and the actuating-arm thereof.

Referring to the drawings inidetail, A is a form-cylinder revolving in the direction of the arrow.

1 is an ink-fountain from which ink is taken by the fountain roller 2 and carried by the 'ductor-roller 3 to the ink-cylinder 4, whereon it is distributed by the distributing-roller 5 and thence carried by the vibrating roller 6 to the inking-rollers 7, revolvingin the direction of the arrows, by which it is spread upon the form on the form-cylinder A, all as customary in cylinder-presses.

B is a gear-wheel provided with the exterior teeth 8, meshing with the small intermediate gear-wheels 7), whose teeth in turn mesh with the interior teeth 9 of the large wheel 0. From the wheel 0 project a series of slotted arms d, each carrying, an inking-roller c', jourmaled at. 10. The inking-rollers i are revolved about their own axes by the miter-gear g h,

actuated by the arms Z, journaledv at 13, and

' the sleeves m, journaled at f and provided at their inner ends with the bevel-gear 70, meshing with the teeth a on the face of the wheel 6. The direction of the revolution of each of these revolubleparts is indicated by the arrows, respectively.

The inking-rollers 11 are pressed out to the ends of the arms 0! by the springs e, against forming part of Letters Patent No. 752,285, dated February 16, '1904.

stun No. 105,375. (nominal I the pressure of which they are forced down into the slots 11 as they ride over the cir'cum--- ference of the form-cylinder A. The arms 41 are provided with the collars 12 on each side of the journals 13, which are rigidly connected with the journals 10 ofthe inking-rollers i, and therefore carry the arms Z inward and outward with the inward and outward motion of the inking-rollers c' in the slots 11, keeping the miter-gear g h always speed of the wheel 0 and that of the form-cyl- I inder A. Such a rate of speed of the wheelc also causes several of the rollers 71 in succession to pass over 'a-given arc of the form-cylinder before it revolves beyond their orbit, thereby securing a better inking. For the same reason it is desirableto place the inkingrollers 21 as close together as is permitted by their inward and outward motion as they ride over the form-cylinder. The gear actuating the rollers 71 about their own axes is adjusted to give them the same rate of speed that they would have if driven only by friction with the form-cylinder A. Y

Ink is fed to the inking-rollers 11 by the inking-belt 14,, which is supplied from the inkfountain 15 by the founta'in-roller-16, ductorroller 17, ink-cylinder 18, distributing-roller 19, and ductor-roller 20.

The operation of the device is as follows: The form (not shown) having been secured to the form-cylinder A is revolved with it in the direction of the arrow on A. It meets the inking-rollers 7, revolving in the same direction and at the same rate of speed. The inking-rollers '3, the fountain, ductor, and distributing rollers 2, 3, and 5, and the inkcylinder i, connecting the same'with the ink-fountain 1, may be actuated by gear (not shown) or by friction. The vibrating roller 6 is ac- Ioo tuated by gear (not shown) in the usual way.

The gear-wheel Bis revolved ata'highrate of speedinthe direction of its arrow and throughwith the form-cylinder A and as they ride over its circumference are forced back into the slots 11 of their respective arms d. The formcylinder A is'provided with a resilient rim or 'buiferfnot shown) to engage the inking-rollrollers.

ers i as they approach the cylinder and pre- Vent-any hammering or jarring of the form or The inking rollers '11 are revolved about their own axes in the direction of their arrows opposite to that of the form-cylinder A by the bevel-gear k, meshing with the teeth a on the wheel B, and transmitting its motion through the sleeves m, the splined' arms Z, and the miter-gear g h. The rate of revolution of the inking-rollers iabout their own axes is the same as would be imparted to them by frictional contact with the formcylinder A,so as to cause the ink to be spread'upon the form without blurring the type or scraping the rollers.

' As the inking-rollers i leave the form-cylinder they are pressed out again by the springs e to the ends of the arms 03 and receive a fresh.

supply of ink from the inking-belt l4, which is fed from its ink-fountain 15 by the set of rollers andink-cylinders 16, 17 18, 19, and 20,

actuated by gear (not' shown) 'or'by friction. The form after being inked as above described comes in contact with the web carried over impression-cylinders (not shown) in ing-rollers c', as they may be actuated by fric tion or by a chain or other well known mechanical devices.

What I claim as new, and desire to secure by Letters Patent, is. 4
